PHP是嵌入在HTML中的一種開源編程語言。 它主要用於創建動態網站，例如博客，電子商務網站等。RasmusLerdorf於1994年創建了它。
CentOS 8 / RHEL 8默認帶有PHP v7.2。
在這篇文章中，我們將看到如何在CentOS 8 / RHEL 8上安裝PHP 8.0。
添加Remi存儲庫
Remi，一個第三方存儲庫，為Red Hat Enterprise Linux提供了多個PHP版本（8.0 / 7.4 / 7.3 / 7.2）。
Remi系統信息庫要求在系統上啟用EPEL系統信息庫。 因此，在系統上安裝最新的EPEL存儲庫自動配置rpm，以啟用EPEL存儲庫。
dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
然後，使用以下命令安裝Remi存儲庫自動配置軟件包。
dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm
輸出：

安裝Remi存儲庫rpm後，列出可用的PHP模塊流。
dnf module list php
您應該看到以下輸出。
CentOS-8 - AppStream Name Stream Profiles Summary php 7.2 [d] common [d], devel, minimal PHP scripting language php 7.3 common [d], devel, minimal PHP scripting language Remi's Modular repository for Enterprise Linux 8 - x86_64 Name Stream Profiles Summary php remi-7.2 common [d], devel, minimal PHP scripting language php remi-7.3 common [d], devel, minimal PHP scripting language php remi-7.4 common [d], devel, minimal PHP scripting language php remi-8.0 common [d], devel, minimal PHP scripting language Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled
在CentOS 8 / RHEL 8上安裝PHP 8.0
啟用php：remi-8.0模塊以安裝PHP 8.0。
dnf module enable php:remi-8.0 -y
輸出：
Dependencies resolved. =================================================================================================================== Package Arch Version Repository Size =================================================================================================================== Enabling module streams: php remi-8.0 Transaction Summary =================================================================================================================== Complete! Switching module streams does not alter installed packages (see 'module enable' in dnf(8) for details)
使用dnf命令在CentOS 8 / RHEL 8上安裝PHP 8.0。
dnf install -y php php-cli php-common
在CentOS 8 / RHEL 8上安裝PHP 7.x
如本文所示，啟用php：remi-7.x模塊以在系統上安裝PHP7.x。
安裝PHP-FPM
如果要在RHEL 8上設置LEMP堆棧，則可能要安裝php-fpm。
dnf install -y php-fpm
安裝PHP擴展
PHP擴展是已編譯的庫，可為您的代碼提供特定的支持。

要在代碼上提供MySQL支持，可以安裝php-mysqlnd軟件包。
dnf install -y php-mysqlnd
現在，以下命令將列出已安裝的MySQL擴展。
php -m | grep -i mysql
輸出：
mysqli mysqlnd pdo_mysql
結論
就這樣。 我希望您已經學會了如何在CentOS 8 / RHEL 8上安裝PHP 8.0。請在評論部分中分享您的反饋。
